The vibration of the wire is not an accidental phenomenon, but an inevitable result of the action of wind. When the wind speed is in the range of 0.5-8m/s, the air flow will form a periodic vortex behind the wire, causing low-frequency and large-amplitude vibration of the wire perpendicular to the direction of the air flow, that is, breeze vibration. When the wind speed reaches 8-25m/s, the wire may experience transverse and high-frequency secondary pitch vibration. Long-term neglect of this kind of vibration can lead to wire fatigue and broken strands, wear of metal fittings, damage to insulators, and even cause major accidents such as circuit tripping and inverted towers in severe cases. According to statistics from the International Energy Agency, the annual maintenance cost of power equipment caused by wire vibration exceeds 3 billion U.S. dollars, and the loss of power outages caused by failures is even more difficult to calculate. At this time, the effect of spiral vibration damper appeared. Spiral vibration damper is not a simple buffer device, but through specific structural design and material characteristics, it actively cancels the vibration energy of the wire and cuts off the hidden dangers of failure from the source.
So, where is the effectiveness of spiral vibration damper? The key lies in the resonance suppression principle and customized adaptation ability of spiral vibration damper. The high-quality spiral vibration damper is made of high-strength aluminum alloy or composite polyurethane material. By installing it near the wire fittings, it uses its own quality and elasticity to generate a reverse force when the wire vibrates, and the vibration amplitude is controlled within the safety threshold. Taking the spiral vibration damper we provided for a power grid project in a country in Southeast Asia as an example, the area is affected by monsoons all year round, the vibration frequency of the transmission line is as high as 12-15Hz, and the annual disconnection rate of the pre-installation line is 8.3%. After the full installation of our spiral vibration damper, monitoring data for three consecutive years showed that the vibration amplitude of the wire was stably controlled below 0.08mm, the strand break rate and equipment maintenance costs were significantly reduced, and the reliability of line power supply was also improved. This kind of case is not an exception. In power projects in more than 20 countries in Europe, Africa, and South America, our spiral vibration damper has achieved zero vibration failure within three years after installation, and has responded to buyers' doubts with practical results.
For B-side buyers, choosing spiral vibration damper is not only choosing a product, but also choosing a complete security system. Compared with the ordinary spiral vibration damper on the market, our products also have three advantages. Respectively, it is a lightweight design, using a new type of composite material, light weight can reduce the wire load, while the installation efficiency is increased by 50%. There is also broadband suppression ability. Our spiral vibration damper can effectively cope with the full frequency band vibration of 0.5-30Hz, covering breeze vibration and secondary pitch vibration, without the need to match other anti-vibration equipment. As well as long-life characteristics, the material has excellent aging resistance, and the life span under normal use far exceeds the industry average, which can significantly reduce the long-term operation and maintenance costs of buyers.
Now, the effectiveness of spiral vibration damper has become an important guarantee for the safety of the power grid. We not only provide buyers with high-quality spiral vibration damper, but also are committed to becoming your long-term partner for power projects.
